Sotheby’s New York created a “Roaring ’20s” theme for its upcoming Magnificent Jewels sale as a celebration to the opening up of the U.S. again after 15 months of closures due to the Coronavirus pandemic.

The 94 lots for the June 9 sale will include white and colored diamonds, Kashmir and Ceylon sapphires, Colombian emeralds and Burmese rubies set into iconic designs signed by heritage jewelry houses. And of course, a jewelry sale wouldn’t be complete without important signed pieces from jewelry houses that include Van Cleef & Arpels, Cartier and Bulgari, as well as René Boivin and Sterlé. Online bidding has already begun with Sotheby’s hybrid online and live auction formula it has been using in response to the pandemic.

The sale will be on public exhibition at Sotheby’s New York galleries from June 4 – 8 as part of Sotheby’s Luxury Week, a series of nine auctions spanning what the auction house says are “the fastest growing categories” in the luxury space.

The top lot of the sale is “The Sienna Star,” a 73.11-carat fancy vivid yellow diamond mounted on a ring with pavé diamonds and a flexible shank by the London-based contemporary jewelry house, G by Glenn Spiro.
